(a) The provisions of this section shall apply in all of the following cases:

(1) When a prisoner is confined in or committed to a county jail, industrial farm, or road camp, or any city jail, industrial farm, or road camp, including all days of custody from the date of arrest to the date on which the serving of the sentence commences, under a judgment of imprisonment, or a fine and imprisonment until the fine is paid in a criminal action or proceeding.

(2) When a prisoner is confined in or committed to the county jail, industrial farm, or road camp or any city jail, industrial farm, or road camp as a condition of probation after suspension of imposition of a sentence or suspension of execution of sentence, in a criminal action or proceeding.

(3) When a prisoner is confined in or committed to the county jail, industrial farm, or road camp or any city jail, industrial farm, or road camp for a definite period of time for contempt pursuant to a proceeding, other than a criminal action or proceeding.

(4) When a prisoner is confined in a county jail, industrial farm, or road camp, or a city jail, industrial farm, or road camp following arrest and prior to the imposition of sentence for a felony conviction.

(b) Subject to the provisions of subdivision (d), for each six-day period in which a prisoner is confined in or committed to a facility as specified in this section, one day shall be deducted from his or her period of confinement unless it appears by the record that the prisoner has refused to satisfactorily perform labor as assigned by the sheriff, chief of police, or superintendent of an industrial farm or road camp.

(c) For each six-day period in which a prisoner is confined in or committed to a facility as specified in this section, one day shall be deducted from his or her period of confinement unless it appears by the record that the prisoner has not satisfactorily complied with the reasonable rules and regulations established by the sheriff, chief of police, or superintendent of an industrial farm or road camp.

(d) Nothing in this section shall be construed to require the sheriff, chief of police, or superintendent of an industrial farm or road camp to assign labor to a prisoner if it appears from the record that the prisoner has refused to satisfactorily perform labor as assigned or that the prisoner has not satisfactorily complied with the reasonable rules and regulations of the sheriff, chief of police, or superintendent of any industrial farm or road camp.

(e) No deduction may be made under this section unless the person is committed for a period of six days or longer.

(f) It is the intent of the Legislature that if all days are earned under this section, a term of six days will be deemed to have been served for every four days spent in actual custody.

[...]

(4) As used in this subdivision, "serious felony" means a serious felony listed in subdivision (c) of §1192.7.

(5) This subdivision shall not apply to a person convicted of selling, furnishing, administering, or giving, or offering to sell, furnish, administer, or give to a minor any methamphetamine-related drug or any precursors of methamphetamine unless the prior conviction was for a serious felony described in subparagraph (24) of subdivision (c) of §1192.7.

(b) It is the intent of the Legislature in enacting subdivisions (b) to (i), inclusive, to ensure longer prison sentences and greater punishment for those who commit a felony and have been previously convicted of serious and/or violent felony offenses.

(c) Notwithstanding any other law, if a defendant has been convicted of a felony and it has been pled and proved that the defendant has one or more prior felony convictions as defined in subdivision (d), the court shall adhere to each of the following:

(1) There shall not be an aggregate term limitation for purposes of consecutive sentencing for any subsequent felony conviction.

(2) Probation for the current offense shall not be granted, nor shall execution or imposition of the sentence be suspended for any prior offense.

(3) The length of time between the prior felony conviction and the current felony conviction shall not affect the imposition of sentence.

(4) There shall not be a commitment to any other facility other than the state prison. Diversion shall not be granted nor shall the defendant be eligible for commitment to the California Rehabilitation Center as provided in Article 2 (commencing with Section 3050) of Chapter 1 of Division 3 of the Welfare and Institutions Code.

(5) The total amount of credits awarded pursuant to Article 2.5 (commencing with Section 2930) of Chapter 7 of Title 1 of Part 3 shall not exceed one-fifth of the total term of imprisonment imposed and shall not accrue until the defendant is physically placed in the state prison.

(6) If there is a current conviction for more than one felony count not committed on the same occasion, and not arising from the same set of operative facts, the court shall sentence the defendant consecutively on each count pursuant to subdivision (e).

(7) If there is a current conviction for more than one serious or violent felony as described in paragraph (6), the court shall impose the sentence for each conviction consecutive to the sentence for any other conviction for which the defendant may be consecutively sentenced in the manner prescribed by law.

(8) Any sentence imposed pursuant to subdivision (e) will be imposed consecutive to any other sentence which the defendant is already serving, unless otherwise provided by law.

(a) Notwithstanding any other law, any person who is convicted of a felony offense listed in subdivision (c) of Section 667.5 shall accrue no more than 15 percent of worktime credit, as defined in Section 2933.

(b) The 15-percent limitation provided in subdivision (a) shall apply whether the defendant is sentenced under Chapter 4.5 (commencing with Section 1170) of Title 7 of Part 2 or sentenced under some other law. However, nothing in subdivision (a) shall affect the requirement of any statute that the defendant serve a specified period of time prior to minimum parole eligibility, nor shall any offender otherwise statutorily ineligible for credit be eligible for credit pursuant to this section.

(c) Notwithstanding Section 4019 or any other provision of law, the maximum credit that may be earned against a period of confinement in, or commitment to, a county jail, industrial farm, or road camp, or a city jail, industrial farm, or road camp, following arrest and prior to placement in the custody of the Director of Corrections, shall not exceed 15 percent of the actual period of confinement for any person specified in subdivision (a).

(d) This section shall only apply to offenses listed in subdivision (a) that are committed on or after the date on which this section becomes operative.

(a) It is the intent of the Legislature that persons convicted of a crime and sentenced to the state prison under Section 1170 serve the entire sentence imposed by the court, except for a reduction in the time served in the custody of the Director of Corrections for performance in work, training or education programs established by the Director of Corrections. Worktime credits shall apply for performance in work assignments and performance in elementary, high school, or vocational education programs. Enrollment in a two- or four-year college program leading to a degree shall result in the application of time credits equal to that provided in Section 2931. For every six months of full-time performance in a credit qualifying program, as designated by the director, a prisoner shall be awarded worktime credit reductions from his or her term of confinement of six months. A lesser amount of credit based on this ratio shall be awarded for any lesser period of continuous performance. Less than maximum credit should be awarded pursuant to regulations adopted by the director for prisoners not assigned to a full-time credit qualifying program. Every prisoner who refuses to accept a full-time credit qualifying assignment or who is denied the opportunity to earn worktime credits pursuant to subdivision (a) of Section 2932 shall be awarded no worktime credit reduction. Every prisoner who voluntarily accepts a half-time credit qualifying assignment in lieu of a full-time assignment shall be awarded worktime credit reductions from his or her term of confinement of three months for each six-month period of continued performance. Except as provided in subdivision (a) of Section 2932, every prisoner willing to participate in a full-time credit qualifying assignment but who is either not assigned to a full-time assignment or is assigned to a program for less than full time, shall receive no less credit than is provided under Section 2931. Under no circumstances shall any prisoner receive more than six months' credit reduction for any six-month period under this section.

(b) Worktime credit is a privilege, not a right. Worktime credit must be earned and may be forfeited pursuant to the provisions of Section 2932. The application of credit to reduce the sentence of a prisoner who committed a crime on or after January 1, 1997, is subject to the provisions of Section 3067. Except as provided in subdivision (a) of Section 2932, every prisoner shall have a reasonable opportunity to participate in a full-time credit qualifying assignment in a manner consistent with institutional security and available resources.

(c) Under regulations adopted by the Department of Corrections, which shall require a period of not more than one year free of disciplinary infractions, worktime credit which has been previously forfeited may be restored by the director. The regulations shall provide for separate classifications of serious disciplinary infractions as they relate to restoration of credits, the time period required before forfeited credits or a portion thereof may be restored, and the percentage of forfeited credits that may be restored for these time periods. For credits forfeited for commission of a felony specified in paragraph (1) of subdivision (a) of Section 2932, the Department of Corrections may provide that up to 180 days of lost credit shall not be restored and up to 90 days of credit shall not be restored for a forfeiture resulting from conspiracy or attempts to commit one of those acts. No credits may be restored if they were forfeited for a serious disciplinary infraction in which the victim died or was permanently disabled. Upon application of the prisoner and following completion of the required time period free of disciplinary offenses, forfeited credits eligible for restoration under the regulations for disciplinary offenses other than serious disciplinary infractions punishable by a credit loss of more than 90 days shall be restored unless, at a hearing, it is found that the prisoner refused to accept or failed to perform in a credit qualifying assignment, or extraordinary circumstances are present that require that credits not be restored. "Extraordinary circumstances" shall be defined in the regulations adopted by the director. However, in any case in which worktime credit was forfeited for a serious disciplinary infraction punishable by a credit loss of more than 90 days, restoration of credit shall be at the discretion of the director.

The prisoner may appeal the finding through the Department of Corrections review procedure, which shall include a review by an individual independent of the institution who has supervisorial authority over the institution.

(d) The provisions of subdivision (c) shall also apply in cases of credit forfeited under Section 2931 for offenses and serious disciplinary infractions occurring on or after January 1, 1983.

(a) Notwithstanding §2933.1 or any other law, any person who is convicted of murder, as defined in Section 187, shall not accrue any credit, as specified in Section 2933.

(b) The limitation provided in subdivision (a) shall apply whether the defendant is sentenced under Chapter 4.5 (commencing with Section 1170) of Title 7 of Part 2 or sentenced under some other law.

(c) Notwithstanding Section 4019 or any other provision of law, no credit pursuant to Section 4019 may be earned against a period of confinement in, or commitment to, a county jail, industrial farm, or road camp, or a city jail, industrial farm, or road camp, following arrest for any person specified in subdivision (a).

(d) This section shall only apply to murder that is committed on or after the date on which this section becomes operative.

(a)(1) Notwithstanding any other provision of law, every person who is convicted of any felony offense listed in paragraph (2), and who previously has been convicted two or more times, on charges separately brought and tried, and who previously has served two or more separate prior prison terms, as defined in subdivision (g) of Section 667.5, of any offense or offenses listed in paragraph (2), shall be ineligible to earn credit on his or her term of imprisonment pursuant to this chapter.

(2) As used in this subdivision, "felony offense" includes any of the following:

(A) Murder, as defined in Sections 187 and 189.

(B) Voluntary manslaughter, as defined in subdivision (a) of Section 192.

(C) Mayhem as defined in Section 203.

(D) Aggravated mayhem, as defined in Section 205.

(E) Kidnapping, as defined in Section 207, 209, or 209.5.

(G) Rape, as defined in paragraph (2) or (6) of subdivision (a) of Section 261 or paragraph (1) or (4) of subdivision (a) of Section 262.

(H) Sodomy by means of force, violence, duress, menace or fear of immediate and unlawful bodily injury on the victim or another person, as described in subdivision (c) of Section 286.

(I) Sodomy while voluntarily acting in concert, as described in subdivision (d) of Section 286.

(J) Lewd or lascivious acts on a child under the age of 14 years, as described in subdivision (b) of Section 288.

(K) Oral copulation by means of force, violence, duress, menace, or fear of immediate and unlawful bodily injury on the victim or another person, as described in subdivision (c) of Section 288a.

(L) Continuous sexual abuse of a child, as described in Section 288.5.

(M) Sexual penetration, as described in subdivision (a) of Section 289.

(N) Exploding a destructive device or explosive with intent to injure, as described in Section 12303.3, with intent to murder, as described in Section 12308, or resulting in great bodily injury or mayhem, as described in §12309.

(O) Any felony in which the defendant personally inflicted great bodily injury, as provided in §12022.53 or §12022.7.

(b) A prior conviction of an offense listed in subdivision (a) shall include a conviction in another jurisdiction for an offense which includes all of the elements of the particular felony as defined under California law.

(c) This section shall apply whenever the present felony is committed on or after the effective date of this section, regardless of the date of commission of the prior offense or offenses resulting in credit-earning ineligibility.

(d) This section shall be in addition to, and shall not preclude the imposition of, any applicable sentence enhancement terms, or probation ineligibility and habitual offender provisions authorized under any other section.
